Matthew 13:10-13, 34-35, 53

Then the disciples came to Him and asked, “Why do You speak to the crowds in parables?” Jesus replied to them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted. [Mark 4:11] For whoever has [spiritual wisdom because he is receptive to God’s word], to him more will be given, and he will be richly and abundantly supplied; but whoever does not have [spiritual wisdom because he has devalued God’s word], even what he has will be taken away from him. [Matt 25:29; Mark 4:25; Luke 8:18] This is the reason I speak to the crowds in parables: because while [having the power of] seeing they do not see, and while [having the power of] hearing they do not hear, nor do they understand and grasp [spiritual things].

All these things Jesus said to the crowds in parables, and He said nothing to them without [using] a parable. This was to fulfill what was spoken by the prophet: “I WILL OPEN MY MOUTH IN PARABLES; I WILL UTTER THINGS [unknown and unattainable] THAT HAVE BEEN HIDDEN [from mankind] SINCE THE FOUNDATION OF THE WORLD.” [Ps 78:2]

When Jesus had finished these parables, He left there.
